To all whom it may concern Be it known that ll, LOUIS HirroLx'rn En MOND Biioo'r, a citizen of the Republic of France, residing at 192 Rue de Vaugirard, Paris, France, have invented certain new and useful Improvements in Apparatus for Sterilizing Water by Means of Ozone, of which the following is a disclosure.

My invention relates to combined apparatus for ozonizing air and sterilizing water and is particularly adapted for use in homes, institutions, etc., where comparatively small plants, requiring a minimum amount of at tention,'are desired. a I

The object of my invention is to provide apparatus of this kind that will be reliable in operation, comparatively simple and inexpensive to construct and which will give an instantaneous flow of sterilized water and which can be put into and out of operation by merely openingand closing a water cock. With these objects in view my invention comprises means for ozonizing air, means for mixing the ozonized air with the water to be sterilized, a cock controlling the delivery of sterilized water, means whereby theopening of the cock will start the apparatus, and

other detail features which I will hereinafter describe.

The preferred embodiment of my invention is illustrated in the accompanying drawings, in "which Figure 1 is a front view of the complete apparatus except the sterilizing chamber;

Fig. 11 is a front view, drawn to a reduced scale, illustrating the assembled apparatus complete;

Fig. 12 is a side view of the apparatus shown in Fig. 11.

Referring in detail to the drawings, the apparatus is connected to the water mains through a pipe at, provided with a stop cock 6. When the latter is opened, water flows through conduit 0 into the transverse canal 0 arranged on the lower side of block 0 and piston d formed of a pressed leather disk is subjected to the pressure of the water. Above the piston (Z there is an insulating block cl above which is fixed a metallic disk 03. When the piston (Z is raised by the water the disk or plate cl will close the cock is turned to turn on the water it raises the member 9 and closes the gap between the terminals 6 6, thus closing the electric circuit. 72. represents a filter which may be employed to remove coarse matter from the water. h is an auxiliary cock for shutting oil the water.

The water flows through conduit 0 into pipe 2' after having passed a regulating cock f, and reaches the injector 2", which by aspiration or suction draws in the ozonized air through tube 2'. The water then acts on the vanes 7 of the water turbine, or motor, which, in turn, rotates the interrupter mounted on shaft 8, a description of which will be given below.

The water, mixed with the sterilizing agent, thatis the ozonated air, after having acted upon the. vanes 7 of the turbines, leaves the turbine casing through pipe 19,

except that a portion of the water is carried beyond theentrance to pipe 19 by centrifugal action; and if this water were left in the turbine chamber it would tend to set up a counter pressure or reaction with the consequence that the rotation of the turbine would thereby be reduced. To obviatetlus, such water as is carried by the entrance-to pipe 19 by centrifugal force, is forced up behind the partitioni, rises within space'7" and reenters the chamber, without pressure, through orifice 7 running along the inside wall of -the chamber and becoming eventually mixed with the water escaping through conduit 19. p T

The lower end of'con'duit 19 is narrowed or tapered at and terminates in chamber 3', where it forms a second water injector-opcrating through tube 19 to relieve any excess of pressure inside the'casing or turbine 7. The water and ozonized air flow from the injector into the sterilizing chamber 30, then out through the discharge pipe 19".

If the vessel to be filled with sterilized water is so contracted around the end 19"- as to prevent the air escaping or the end 19 is permittedto extend into the liquid, there will be a backing'up'of the liquid in the apparatus. To prevent this happening an orifice is placed in the wall of the chamber j, which is closed under normal conditions by a spherical valve j of the pendular type and which is held down only by its weight. The arrangement is such that if the liquid should rise in the apparatus, it will. be impossible for the motor or generz tor to be flooded because the Water will flow through the orifice in box j by raising the spherical valve j. 1

It will be seen from the foregoing that auxiliaryinjector 9" has two distinct functions, (l)it prevents counter pressures or reactions in the turbine casing by sucking off any excess ofozonated air, this excess of ozonated air beingutilized for sterilizing purposes by being brought in contact with water previously treated; and (2) it prevents any water rising in the system and flooding the apparatus.

The ozone generator proper is formed of insulating laminae q, COIlStitLlting dielectric elements interposed between the conducting laminationsl between which silent discharges pass. The conducting layers Z are preferably made of metallic tissue and terminate in tail pieceshaving holes through which the pins m and m pass. These pins constitute the two terminals by which ourrentv is supplied to the electrodes. The sleeves n and n on the pins m m serve to maintain the proper distance between plates Z and Z. The rings 1" of insulating material operate to space the dielectric plates from each other. Spark terminals t and 25 are mounted on the pins 722. and m. and are so disposed as to permit discharges passing between them in case the potential has a. tendency to rise to such an extent as to damage the apparatus. The cover 0 is mounted so as to hold the electrodes and dielectric. plates in position. The nuts .9 and s operate in connection with the springs 12 and p to hold the cover and plates of the gene ator in position. The dielectric elements 9 are provided with openings arranged to permit the circulation of the air to be ozonized. The air enters at (Fig. 3), circulates across the plates by passing through-openings w and. u", and leaves through orifice 14.

The electrical apparatus required to operate the ozonizer is assembled in a suitable box or frame (see Fig. It comprises a. transformer '0, inductance or loading coils Q), condenserso and switch Q all connected and arranged as shown in the diagram of electrical connections, Fig. .6. Referring to this figure it will be seen that the switch d", e, c, actuated either by the pressure of the water or else by the cock, as above described, is placed in onelead of. the local supply circuit, the'latter comprising the indicator lamp K, reactance coils o, condenser 2, transformer o and switch 'v for connecting the circuits for continuous or alternating current, and finally the rotating interrupter X.

As shown, the switch '0' is set for operation with continuous current, and the current coming in over wire Z, traverses lamp K, goes through wire 2 into inductance '2) and through wire 3, switch o and wire 4-. It then goes to the second inductance o and,

after traversing the same, goes to the 0011- denser 'v, thence to the primary circuit of thetransformer and finally into return lead 5. The fore-goingdescription is made on the assumption that the rotating interrupter or breaker is on an insulating contact; when it is on a conducting contact a short circuit. is produced by wire 6 and the interrupter through which the primary of the transformer discharges. If the apparatus is connected with an electric main carrying alternating current, thearms of switch 71 are on contacts A and the coils 2: are connected in parallel in lieu of in series. and the operation is otherwise the same.

'-I will now describe rotating breaker or into which a disk 10 is secured. This disk is 123 made of ebonitc or some other insulating material and on its inner face there is placed a small metal plate 23 insulated from the disk 10 by the ebonite disk 24%. The shaft 22 is screwed into the plate 28 and carries a brush-holder 11. The shaft 8, by its rotary motion, drives shaft 22, which, in turn,

rotates the brush-holders 11 and the brushes cylindrical box 14 press-fitted around cylindrical part 14. On the inside wall of cylindrical box 14 and opposite brushes 12 are placed contacts 21 and 21, which are alternately insulating and conducting. Hence the rotation of brushes 12 produces an alternate closing and opening of the electric circuit. The columns 17 serve to support a bar 20 on which the spring contact 18" is placed.

The brushes, due to their friction with the insulating contacts (which are made of fibrous material) become impregnated with fiber whereby naturally their contact with the metallic contacts is impaired. In order to remedy this, one of the contacts 21, over which the brushes wipe, is made of emery, corundum or some other abrasive material adapted to clean the brushes as they rotate.

The duration of contact between the oz0nated air and the water to be sterilized is, as is well known, an essential factor in the operation of a device of this kind. In the apparatus above described, the water to be sterilized is mixed with the ozonized air in turbine 7, Which is sufficient to sterilize good filtered Water. In practice, however, the duration of contact may be lengthened by mounting one or a plurality of baffle boxes or sterilizing chambers 3O between the generator and the discharge orifice 19".

These, as indicated in Figs. 9 and 10, are

1 formed of a metallic plate 30 on which baffies 31 and 32 are soldered; the whole is then placed inside a box 34 to which the ends of tube 19 for the circulation of water and 'ozonized air are soldered. The front face of the box is formed of a glass piece 33 through which the circulation of the water inside the box may be observed. To finish the mounting the bent-over part 30 of bottom 30 is soldered fiat onto the frame of the box 32.

The operation of my improved device will be obvious from the foregoing description. It will also be obvious that modifications and changes may be made in the preferred embodiment described above without departing from the scope of my claims.
